Can you sue for adultery in Wisconsin?

No – the ability to sue for adultery is a common misconception. Adultery is still technically a criminal misdemeanor punishable with a potential fine of up to $10,000. People mistakenly believe that if their spouse commits adultery they get $10,000. If a district attorney would ever prosecute someone for adultery (which I highly doubt would every happen) any fine would go to the State of Wisconsin.
